TocZZ whomit may concern .,--Be it known that I, JOHN BAYNE, a citi- `zen. of the United States of America, and residentofWheeling, county of hio, and West Virginia, have invented cern tain new and useful Improvements in internal-Combustion Engines, olf which the following is a speciicatioii. i

'Thisinvention pertains to certain'new` and improvements' in internal combustion f engines,'and comprehendsthe provisiooof an engine of this type of simple and ecdogoniiand one having v forin- -of valve structure which is completely .opened to the inlet and en haiist permitting the instantaneoiis-l entry of achargeand like exhaust of the burnt or spent' gases.. A-urther object is to provide an engine character' .mentioned wherein pro- -"v'is'ion is made fbi' the quick' direct discharge .o the waste, or exhaust, gases, the practical elimination of bach pressure and in a relative walls `from heat,

" 'oyerheating in the ordinary types of enginebeing in most cases due to the fact that 4the areas of the discharge passages are unduly restricted, resulting in theretention of 3'0 v'much of the heat generated by the explosion.

Afu

rther'object is to .provide an engine wherein'the employment of puppet valves withjtheir attendant springs and hammerf ing noises are wholly 85. whereinl frictionv of 'V attendant wear and necessity for lubrication,

the moving parts, with .is reduced to a minimum. A still further object of the invention is to provide a structure in which the parts ca'nbe easily and 'quickly taken apart to permit of cleaning thereof. A further object within the contemplation to provide a valve for operates over al water and which, consequently, is notsubjected to the high temperatures incident tocontact ordinary types of internal combustion eni? gines.

With these and other objects Vin view, the invention resides in the features of construe* arrangement of parts, and combinaof elements which will hereinafter he` described, reference being had to the in whichtions through al nevel;

resulting in' dispensed with and' fhaust outlet with the walls of the Figure l is a transverse section taken an engine cylinder constructed in conformity with my invention; Fig. 2 is a top plan view'of a four cylinder engine embodying my invention; and Fig. 3 is a side elevation of the same partly in lungi tudinal section.

he invention is shown applied to a four cylinder engine in which the crank case 1 supports the cylinders 2, but one of which latterlwith its associated parts, will, however, b e described. As shown in Fig. l, w ich is a section on line 1-1, Fig. 2, each /cylinder has water jackets 8 and ai encir-4 cling its side walls and top, respectively, and a sleevev valve 5 which closely embraces andv slides over the periphery of the annular water jaclret'ed portion of the cylinder. The sleeve valve 5 is formed'with a circumferential row of ports 6 for register with a corresponding row of ports 7 formed in the cylinder 2 adjacent to the upper end thereof. To the upper end of the cylinder is secured a guide head 8, an inwardly extending flange 9 of the latter being bolted to the upper end of the cylinder, as shown. an inner cylindrical wall 410 of said head 8 closely embraces the sleeve valve 5, acting as a guide between which and the cylinder wall said valve operates. The head 8 is formed with an annular channel therein which communicates with a source of gas supply through a tubular side entrance 11, which isiclosedon its under side by the end of the slide valve 5 to constitute an intake passage 11; and said head has also an ex 12 which communicates with an annular exhaust chamber 13 formed in said Ports 14 lead' from said exhaust chamber through the wall l0 for'registry with the ports aiid 7 hereinbefore mentioned.

-The piston 15 has its crank-rod 16 connected to the crank shaft 17 and the `latter has a gear 18 suitably located thereon in mesh with an idle gear 19 which .in turn 20 on a shaft 21,

a single revolution to two revolutions of the crank shaft, whereby the cam moves through an are of 90 on every stroke of the piston. A bell crank lever 23 is pivoted -to an arm 211 which extendsoutwardly from the cylinder and has an anti-friction roller 25 on one of its ends in bearing contact with the periphery o f the cam 22, a retractile coil spring 26 being secured to the bell crank and to a suitable fixed part, as the casing 27, to cause the roller 25 to engage with the periphery of the cam at all times. The opposite arm of the bell crank lever is bifurcated, as indicated at 28 in Fig. 3, and is connected by means of a pair of links 29 to the lower end of the sleeve valve 5, or to a collar 30 'that is inset into the lower end of said sleeve valve, Aas shown. The casing 27 aforementioned `incloses the cam 22 and associated parts, being adapted to contain oil or other lubricant, and has a hinged connection, as at 31, with a cover 32 which extends upward to a suitable height, as to the lower ends ef the walls 10 of the guide heads 8. A cover 33 of any appropriate character is secured on the opposite sides of the cylinders between the lower ends of the walls 10 offguide heads 8 and the crank case 1. The cam 22 is formed so that an arc'of 180 of the periphery thereof has the same radius throughout, and, as a consequence, the sleeve vvalve 5 is held stationary during the compression and explosion strokes in a neutral position-that is, in such a position that the upper end thereof maintains both the cylinder ports 7 and the exhaust ports 14 leading into the exhaust chamber 13 closed. When the piston has reached the end or limit of its explosion stroke, the roller 25 mounts a' 90 arc of the cams periphery,

which arc is more remote from the shaft 21, .v thus instantly elevating the sleeve valve 5` to a point where the ports 6 thereof register with the cylinder ports 7, and with the exhaust ports 14, permitting` the burnt or spent gases to exhaust on the return upward stroke of the piston. At the limit of the` upward exhaust stroke of the piston, the," roller 25 drops to a substantially straight chord-like surface or portion of the periphery of the cam, in which position it is nearer to the shaft 21, and the sleeve valve 5 is thus instantly moved downward to a position where an internal annular passage 34 provided at the upper.' end of the sleeve valve 5 registers with the cylinder ports 7 whereupon a fresh charge of gas is admitted from the annular inlet'chamber 11. At the limit of the intake stroke the roller 25 again mounts the 180 are of the periphery of the cam 22, instantly raising the sleeve valve 5 to a neutral position. When it-is desired toremove the sleeve valve 5 for any. purpose, it is merely neces sary to remove the guide head 8 andto disvrious piston strokes for effecting the instantaneous and timely admission and exhaust of the gases; an engine which is practically frictionless and noiseless in its operation, and which has but few parts liable to become out of order.

Having thus described my. invention, what 1 claim as new, and desire to secure by Letters Patent, is- 1. In an internal combustion engine, the combination with a cylinder having periph-l eral ports, of a guide head securedto the outer end of the cylinder and disposed in encircling relation thereto at a spaced diS- tance therefrom, said guide' head being formed with an intake passage and exhaust ports therein for communication with the cylinder ports, a sleeve valve sldably mounted in thespace between said guide head and the cylinder and provided with ports for reg-V 2.
